What it saw was the Lord of Ten Thousand Swords' attack; without using any magical artifacts, he unleashed a full-force strike that shattered a gathering place for Dark Death Beasts, along with the surrounding mountain range.

It will die, that's for sure. Facing the Master of Ten Thousand Swords Pavilion, it will definitely die.

It needs to find other members of its own kind, those whose strength is equal to or even greater than its own.

Perhaps, at this moment, they need to join forces to face this unprecedented crisis.

"Your idea is quite good, but unfortunately, it can't be done."

An aged voice echoed in his ears, devoid of any emotion, yet it sent chills down his spine.

"who?"

I turned around, but saw nothing.

No, perhaps it's not quite right to say that; it did indeed see some entirely new changes taking place here.

Corpses, a large number of corpses, accompanied by gushing blood.

As the dominant species, it has an abandoned human city as its lair, and when it travels, it is accompanied by a group of undead beasts.

But now, when it turned around, all its followers were dead. If it weren't for that voice, it wouldn't even have realized what had happened.

Who is the enemy? When did they make their move? What are their specific capabilities?

It knew nothing about the three questions.

The only clues to the enemy's success were the wounds on the corpses on the ground and their calm expressions; each attack was a fatal blow, and their weapons were extremely sharp.

They lost their last consciousness before they even realized they were dying.

Fear stems from the unknown. Finally, the pupils of this superior, the Dark Beast, shrink as it repeatedly uses its sense of smell, hearing, sight, and its animal instincts to search for the enemy lurking in the shadows.

"How is this possible? I couldn't even sense a presence?"

Nothing was gained.

It found nothing; if it weren't for the corpse on the ground and the sound, it might have thought it was its own imagination.

"Who are you? Show yourself!"

"OK……"

If it hears a sound from behind, it can pinpoint the location.

"Go to hell!"

He turned around abruptly, and at the same time, his entire body launched a fierce attack on that spot and the surrounding area.

"Boom..."

The rocks were shattered, and the powerful force tore apart the already split mountainside, quickly leveling everything in front of them.

However, there was no feeling of hitting the target.

Moreover, it wasn't until the attack was over that it realized it had lost two of its field of vision.

"What?"

It saw two heads on the ground; those were its own heads, which had somehow separated from its body.

"Is that all? How disappointing, monster."

With that sound, the vision disappeared one by one until finally, its main consciousness and body broke apart, and its head, spinning in mid-air, saw a figure in black robes.

Mayer Louis III, a participant in the Holy Grail War and an assassin.

This is the ultimate assassin, this is top-notch infiltration; he will kill every target he sees.

That way, no one will discover that he has infiltrated.

"Although this monster won't pose a threat, my competitor is really formidable."

He must be a swordsman (Saber). People like that have terrifyingly sharp intuition. I wonder if I could successfully assassinate him.

He was preparing to leave the stronghold of the powerful Dark Death Beasts; the abandoned human city had already been cleared out.

Not long after the Dark Beast left, the assassin used his Noble Phantasm on the city, and now he is catching up to finish it off.
